Abstract
Abstract The synthesis of some substituted 3-methyl-1-nitro phenothiazines via a Smiles rearrangement is reported. 2-Amino-5-methyl 3-nitrobenzenethiol was prepared by alkaline hydrolysis of 2-amino-6-methyl-4-nitrobenzothiazole and condensed with o-halonitrobenzenes to obtain diaryl sulphides. They were converted by formic acid into formyl derivatives which by a Smiles rearrangement give the corresponding phenothiazines.
